114 ON THE LIFE-HISTORIES OF AUSTRALIAN COLEOPTERA, 



margins of segments ; mouth parts and jaws black, head romuled 

 in front, broad behind, base of forehead with a broad ferrui,nnous 

 band extending backwards round the sides, a short furrow in 

 centre, with a deeper fdrrow on either side, the summit broad, 

 projecting, bluish-white, finely transversely striated ; thoracic 

 segments wide but short, the last with warty markings on the 

 upper sides, first six abdominal segments deeply and widely con- 

 stricted, the summit with a depression in centre surmounted on 

 either side with an oval warty excrescence ; 7th short, cylindrical, 

 smooth; 8th twice as long as 7th; anal segment small, conical, 

 depressed at the tip, with five short stout spines on the upper side 

 forming a triangle pointing downwards ; corresponding warty 

 patches on the underside of segments. 



The larva feeds upon the stems of Eucalyptus corymbosa, 

 attacking them about a foot above the ground ; it bores upward, 

 holluwing out the branches ; it then turns downward and gnaws 

 I'ight round the top of the stem where it first entered, thus killing 

 the branch. It is a common sight ou the sandhills in the neigh- 

 bourhood of Botany, about August and September, to see a dead 

 bush standing out in every patch of this Eucalypt, and which 

 when pulled readily snaps off short at the gnawed ring. The larva 

 feeds downwards towards the roots just before pupating, and will 

 generally be found in the stem a few inches above the ground 

 when in the pupal stage. 



The beetle is 16 lines in length, of a rich reddish-brown colour ; 

 the head long and slender; thorax long, cylindrical, finely and 

 deeply striated with transverse corrugations, but covered with fine 

 pale buff hairs almost obscuring them ; the whole of the elytra, 

 legs and under.side covered with a fine close pale buff pubescence, 

 the fore part of elytra from the shoulders to the fore legs broad, 

 deeply punctured with irregular coarse striae, the edges of which 

 are fringed with a pale buff pubescence giving it a handsome 

 wavy pattern; the rest of elytra densely covered with pubescence, 

 and tapering towards the tip of the abdomen, the tips arcuate 

 forming a double tooth on either side. It is a long slender beetle 

 resembling Uracanthus triangularis in form and habits ; nor is it
